cpt_ri_F5 By this I mean if you had pool_1, pool_2, and pool_3 each with 2 pool members and you wanted to send the same traffic to all of them then why not just take the 6 pool members and add them all to one pool? This would accomplish your task of balancing to each pool member with the exception that instead of balancing to 1 pool member in each pool simultaniously you would only balance traffic to one pool member for each connection, depending on your load balancing method and various other configuration options. After it's all said and done, I do not believe you can balance to multiple pools simultaniously for 1 connection but if it was three unique connections with the same information then I suppose you could split it to multiple pools based on application information such as, source IP, destination IP, HTTP header information, and various other fields using an iRule.
